Business Address

Flat, Shaped and Round Wire ASTM B152, ASTM B747, QQ-C-576


Electrical/electronic and solar applications where strength is not required. Additional applications are downspouts, gutters, roofing, gaskets, heat sinks, busbars, nails, printing rolls, rivets, etc. parts.


In general, copper alloys exhibit good to excellent corrosion resistance and high thermal conductivity and very high electrical conductivity. Pure copper's electrical conductivity is so high that many metals are measured against it in the form of the IACS (International Annealed Copper Standard).
